| Methods | Randomised clinical trial, China | |
| Participants | 69 hospitalised adults undergoing gastrointestinal surgery, at nutritional risk due to major surgery Male:Female = 46:23 Mean age = 49.3 years Exclusion criteria: Unclear |
|
| Interventions | Experimental group 1: Enteral and parenteral nutrition: Enteral nutrition with Supportan (Sino‐Swed Pharmaceutical Corp. Ltd) by using nasogastric tube. (Energy 543 kJ, protein 5.85 g, fat 7.2 g, carbohydrate 10.4 g, sugar 3.6 g, fatty acid 0.3 g, dietary fibre 1.3 g, mineral substance) (n = 22) Experimental group 2: Parenteral nutrition with Novamin (N 8.5% amino acid injection, Sino‐Swed Pharmaceutical Corp. Ltd), non‐protein calorie supported by glucose and fat emulsion (Sino‐Swed Pharmaceutical Corp. Ltd) on a one‐to‐one ratio, plus electrolytes, vitamin and microelement, total 3L were infused through peripheral or central vein within 10 hrs. (Energy 120 kJ/kg/day, N 0.15 g/kg/day; NPC:N = 150:1)(n = 23) Control group: conventional infusion with glucose (50 ‐ 100 g/L), total energy 250 ‐ 300 kJ/day(n = 22) |

| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Not described |
| Allocation concealment (selection bias) | Unclear risk | Not described |
| Blinding of participants and personnel (performance bias) All outcomes | High risk | Participants and personnel were not blinded. |
| Blinding of outcome assessment (detection bias) All outcomes | Unclear risk | Not described |
| Incomplete outcome data (attrition bias) All outcomes | Unclear risk | The number of participants with incomplete data was not reported. |
| Selective reporting (reporting bias) | Unclear risk | No protocol could be obtained and the trial did not report on all‐cause mortality. |
| For‐profit bias | Unclear risk | It was unclear how the trial was funded. |
| Other bias | Low risk | The trial appeared to be free of other components that could put it at risk of bias. |
